Hi,
I have been noticing this that when ever a song starts with vocals its pretty loud but as soon music jumps in the volume adjust itself to a very noticeable decrease, is there anything I did wrong in DSP or may be playback??
By the way I have NAD D1050 DAC from which XLR to Rokit 8 and RCA to WOO WA3 amp.
Thanks for the help in advance.
What you're describing sounds like clip protection is engaging. Do you use any DSP that boosts volume (i.e. equalizer with positive gain, etc.)? If you use DSP that boosts volume, it will potentially drive the output into clipping, and that's why JRiver includes a clip protection function to prevent this from happening. You can confirm that this is happening by watching the audio path dialog window while this phenomenon is happening. It should say if clip protection is engaging.
If this is your problem, here are some ways to fix it:
1) Change your DSP settings so there is no net gain; if you want to boost some frequencies, turn the whole channel down by the same amount to avoid clipping. In the graphic equalizer, you can do this by turning down the "pre-amp" slider. In the parametric equalizer, you can do this by using the "adjust the volume" filter.
2) Use internal volume and set a max volume. Using internal volume gives JRiver much more headroom for DSP; if you use internal volume and set a maximum volume lower than 100%, you can help prevent this from happening. If you turn on the volume leveling feature, that will also usually provide significant additional headroom, especially in combination with internal volume.
If you can post what kind of DSP you're using, I can provide more specific advice.
